Check Engine Codes from a '92 Saab 9000. Either I suck at reading them, or they are displaying weirdly. First 20 seconds or so is the normal "ignition on" blink codes- here it's 4 blinks indicating knock sensor (I think) After that, I use my switch to ground the diagnostic port connector and get the first code. I activate the switch once more at about the 40-second mark (I think) and again some time later. Finally, I activate it once more and get the 3 blinks, indicating it's done with the codes (I think). If anyone can help decipher them, it'd be greatly appreciated!
